Why use PRG0_PRU0_GPO/Y1 as GPIO is conflict with PGR1_PRU1_GPO14/AA11.Thanks

Hello,

Please refer to Table 5-1. Pin Attributes in the datasheet for AM64x: https://www.ti.com/lit/ds/symlink/am6442.pdf

There are two GPIO modules for AM64x, GPIO0 and GPIO1. As seen in the datasheet, the PRG1_PRU1_GPO14 GPIO signal is on GPIO0_79 no GPIO1_79. If you want to use both GPIO modules, then you need to make two GPIO modules in sysconfig with "+ADD" at the top.

Thanks,

Anshu

Understand. Is there any difference between GPIO_0 and GPIO_1? I have distribute all my GPIO to GPIO_0 module.

And is there and difference between using E19 as GPIO or using AA11 as GPIO?Thank you.

It’s an urgent question.

Hello,

There is no difference between the GPIO0 and GPIO1 modules.

E19 and AA11 are two different pins on the SoC. They both function as GPIOs exactly the same.

Best Regards,

Anshu
